Mechanical Engineer
About Us
Array Labs builds advanced radar systems to help humanity understand and respond to changes across the physical world.
We're launching a coordinated fleet of radar satellites to create a high-resolution 3D map of the Earth, updated in real time, enabling faster, smarter decision-making for government and commercial organizations supporting disaster response, infrastructure resilience, and mission-critical geopolitical intelligence.
We design and build our satellites end-to-end, producing the world's most advanced earth observation satellites. Our fleet will deliver unprecedented levels of accuracy, coverage, and responsiveness to power critical insights precisely where they're needed most.
As a Mechanical Engineer, you will own the mechanical design of Array's SAR imaging payloads and satellite subsystems, from concept through flight. Spaceborne radar hardware has to survive launch loads, hold tight tolerances across integrated assemblies, and perform reliably in a thermal-vacuum environment, all while meeting tight mass and volume budgets. You will design structures and assemblies in SolidWorks, run structural analysis to verify launch load and stiffness requirements, and work hands-on through fabrication, integration, and test. You'll coordinate with vendors and machine shops to get flight-quality hardware built, and work closely with RF, electrical, and systems engineers to integrate the payload with the rest of the spacecraft.
As part of our quickly growing engineering team, you will play a critical role in building the world's most advanced radar satellite constellation, one that will significantly improve humanity's ability to rapidly and comprehensively understand our changing planet.
Responsibilities
